What is the molecular weight of Hpmc K15m?
Step 1: Understand the concept of molecular weight .
Molecular weight is the sum of the atomic weights of all atoms in a molecule. It is expressed in units of atomic mass units (amu) or daltons (Da).
Step 2: Know the chemical structure of Hpmc K15m .
Hpmc K15m is a hydroxypropyl methylcellulose polymer. It is a white to slightly off-white, odorless, and tasteless powder. Its chemical formula is (C56H108O30)n, where n is the degree of polymerization.
Step 3: Determine the degree of polymerization .
The degree of polymerization of Hpmc K15m is 1300 to 1500. This means that it has 1300 to 1500 repeating units of (C56H108O30) in its molecule.
Step 4: Calculate the molecular weight .
To calculate the molecular weight of Hpmc K15m, we need to know the molecular weight of (C56H108O30). .
Step 5: Look up the atomic weights .
We can look up the atomic weights of carbon, hydrogen, and oxygen in the periodic table. .
Carbon (C) has an atomic weight of 12.01 amu. .
Hydrogen (H) has an atomic weight of 1.01 amu. .
Oxygen (O) has an atomic weight of 16.00 amu.
Step 6: Calculate the molecular weight of (C56H108O30) .
To calculate the molecular weight of (C56H108O30), we need to multiply the number of atoms of each element by its atomic weight and then sum up the results. .
56 carbon atoms x 12.01 amu = 673.56 amu .
108 hydrogen atoms x 1.01 amu = 109.08 amu .
30 oxygen atoms x 16.00 amu = 480.00 amu .
Total molecular weight = 673.56 + 109.08 + 480.00 = 1262.64 amu .
Step 7: Determine the molecular weight of Hpmc K15m .
To determine the molecular weight of Hpmc K15m, we need to multiply the molecular weight of (C56H108O30) by its degree of polymerization. .
Molecular weight of (C56H108O30) = 1262.64 amu .
Degree of polymerization of Hpmc K15m = 1300 to 1500 .
Molecular weight of Hpmc K15m = 1262.64 amu x 1300 to 1500 = 1.639 to 1.894 million Da .
Conclusion .
The molecular weight of Hpmc K15m is 1.639 to 1.894 million Da.
